Question

Considering the process parameters controlling material flow in extrusion-based systems, if you want to minimize the attachment/adhesion of support material at the interface regions (between model and support material), assuming primary support material, the best approach would be:

Group of answer choices

a. Increase nozzle diameter, decrease material viscosity, make print/scan speed faster when printing the interface regions than when printing anything else

b. Increase feed rate, increase temperature, use an enclosure on the printer

c. make print/scan speed faster when printing the interface regions than when printing anything else, all other parameters stay the same

d. make print/scan speed faster when printing the interface regions than when printing anything else, use an enclosure on the printer, increase feed rate, increase infill density

Answer 1

1. In extrusion based system, the problem of attachment and adhesion of support material is because of slow feed rate and low temperature. This can be solved by

B. Increase Feed Rate, Increase Temperature, Use an enclosure on the printer.

​​​​​​Because increasing feed rate and increasing temperature will help in achieving better stability and extrusion. Higher temperature will ensure lower viscosity and will help in achieving lessee adhesion.

The outer enclosure will help in saving it from the effects of surrounding. Enclosure of surrounding will help in restricting the influence of surroundings.
